Initially diagnosed with a partially torn UCL in his throwing elbow, the veteran right-hander now finds himself on the Yankees' 60-day disabled list.

Pineda agreed to undergo the operation Monday after having his injured right elbow examined in Cincinnati by Dr. Timothy Kremchek, who agreed with the Yankees' original recommendation for surgery. The typical timetable for an eventual return is around one year - if not longer.

Pineda, 28, was 8-4 with a 4.39 ERA in 17 starts for the Yankees this season, and 31-31 with a 4.16 ERA in 89 total starts for the team over the last four seasons.

Yankees starting pitcher Michael Pineda sits in the dugout. Over the course of an even 680 innings of work, he has accumulated a 4.05 career ERA in addition to a 40-41 record. He arrived in the Big Apple in 2014.
